We’ve been getting a lot of questions about the unusual weather and early blooms this winter, so we decided to check in with one of our horticulturists, Laura Swain, to get the scoop.</p> Why are we seeing early blooms?</h4> We are currently experiencing the warmest and driest winter on record with an average temperature of 43 degrees! Many of our beloved early season plants have evolved in more temperate regions of the world. In the late summer and fall, all plants form buds – or tiny packets of densely stored energy for fast growth in the spring. These buds are typically covered in modified leaves, called bud scales, that keep the buds warm and cozy during winter months. Some plants have already met their dormancy requirements, and the warm days (and nights!) trick the plants into thinking it’s spring. </p> Is this bad for the plants?</h4> The risk is that here in Colorado, we will likely get another deep cold spell before winter is over. When this happens, if plants have already opened those bud scales, they become susceptible to winter burn and dieback. This is rarely enough to kill a plant. They may need some extra pruning in spring. This applies primarily to woody trees and shrubs. For herbaceous perennials, plants may expend some extra energy with early winter growth and subsequent dieback but typically have enough stored energy in their roots to carry on when spring finally arrives. </p> While early flowering itself is not detrimental to overall plant health, there is </em>another risk we should be aware of: what is happening below ground. During winter dormancy, plants stop growing above ground shoots, but roots are still busy growing and storing energy. When winters are very dry and warm, many root systems (and bulbs) can suffer. This is especially concerning for newly planted trees, shrubs, perennials and bulbs. </p>
